Hello, I'm Nythar. An edit that you recently made to Collision theory seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Nythar T . C 06:41, 27 July 2022 (UTC)
